I'm only an occasional cacher (in part due to being married to a geo-muggle, who prefers to shop ), and I too have placed a vacation cache (http://www.geocaching.com/seek/cache_details.aspx?ID=59363) , however, in the past five years I have visited the spot 3 times a year on average!
I do get to Scotland almost as frequently, however, I only get that far north for the big Whisky Fest at Hogmanay . I will look after these caches on a relatively infrequent basis, and will endeavour to convert my hosts to cachers on 31 December... any contributions to the whisky fund will be greatly appreciated !
